What is the primary characteristic of a Transient Non-Community Water System?

The defining feature of a Transient Non-Community Water System is its focus on providing water in locations frequented by individuals who do not typically stay for an extended period. This type of system is designed to serve water to the public at sites such as campgrounds, rest areas, or parks—places where people visit temporarily.

Transient Non-Community Water Systems do not operate year-round or serve a stable residential population, which distinguishes them from other water systems that cater to permanent residents or industrial applications. Instead, their primary aim is to accommodate transient populations, making option C the most accurate description of these systems.
